Not to sound like a complainer, but what you say is true, and unfortunate for Nuendo users.
To buy an app that is about 4 times the price and then also buy it’s “little” brother as well in order to get features that improve workflow around 6 months sooner is just weird.
Along with NEK, it’s such an odd approach to the Steinberg product line:
Step 1. Pay a fourfold premium for the most expensive DAW app going (Nuendo).
Step 2. Then pay a few hundred more to get the features already in the 1/4 price, lower level version (Cubase).
Step 3. Then go ahead and buy the lower priced version to get improvements far sooner than the expensive version. Keep in mind that, even after you’ve done this, thereby paying for and gaining the features in Nuendo NEK, you will still need to do Step 2 above. Otherwise, your projects will not be compatible between the apps.
Not how I would do it. Nuendo is great, but the logic (or lack thereof, IMO) of how it’s sold and developed are beyond me.
